The kernels are a side product of the olive oil production and are obtained through compression of the olive in the oil mill and subsequent separation from shell and pulp rests. Thanks to modern centrifugation machines, the crashed kernels are clean and free of any dust or impurities.
After processing, the kernels have a residual humidity of 9-12 %. Olive stones have a higher calorific value (5.6 kWh/kg) compared to air-dried wood (4–4,4 kWh/kg).
Olive kernels are an alternative biomass fuel to wood pellets. As a granulate, they are suitable for biomass boilers, wood gasification plants, cogeneration units and thermal power stations.
Olive kernels are 100% natural, contain no additives and have an oil content of approx. 0.3%.
